DNA Structure and Replication

Front

What is the structure of DNA?

Back

DNA is a double helix made up of two strands of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What base pairs with Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What base pairs with Cytosine in DNA?

Back

Guanine (G) pairs with Cytosine (C).

Front

What is the role of DNA in living organisms?

Back

DNA serves as the blueprint for the traits and functions of all living things.

Front

Where is DNA located in eukaryotic cells?

Back

DNA is primarily located in the nucleus of eukaryotic cells.

Front

What is DNA replication?

Back

DNA replication is the process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate DNA replication and the preservation of genetic information.

Front

What is the function of the enzyme DNA polymerase?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand during replication.

Front

What is the difference between leading and lagging strands in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.
